'WINDOW REGULATOR.

Application filed my 11,

This invention relates to devices adapted to open and close windows such for instance 7/ as those in closed automobiles in which the window is slidable into and out of a suitable window well.

The principal object of the invention is the production of a window regulator of the above character which shall be simple in construction and easy of installation.

A further object of the invention is the production of a window regulator of the above character which shall be so constructed as to always exert an effort centrally of the window for raising or lowering the same whereby the possibility of the window jamming in or against one of its guides is eliminated.

Further objects and advantages of the invention will appear from the accompanying description.

In the accompanying drawings in which a ractical embodiment of the invention is il- Fig. 5 is a vertical cross-section on the line 5 5 of Fig. 4.

. Fig. 6 is a v ew similar to Fig. 4 but showing the device in a different position.

eferring in detail to the several figures of. the drawings:

The side members of a rectangular frame are indicated at 1 which frame may, if so desired, be the frame of a vehicle door. These side members are provided at their lower portions with inner and outer. walls 2 and 3 respectively extending thereaoross and fastened thereto in any desirable manner to form a window well into which a window 4 is vertically slidable in suitable channels or guideways 5 with which said side members are provided.

A supporting plate is indicated at 6 and is secured to one of said side members within the window well preferabl by suitable screws as shown in Fig. 1. ounted in said plate and extending through the wall 2 is 1925.- Serial No. 29,631.

a stud shaft 7 carrying on one end a crank or handle 8. Said stud shaft also carries a pinlon 9 and the end of said shaft is reduced as illustrated and extends through an elliptlcal slot 10 of a plate 11 and is held in engagement with said slotby a headed screw 12 screwed in the end of said stud shaft7.

The plate 11 has fastenedthereto by suitable rivets anoperating arm 13 provided with a slot 14. receiving a headed pin 15 which is mounted or screwed to the support-.

' out of the window well the crank or handle 8 is rotated in the proper direction'and motion is transmitted therefrom through the shaft 7, inion 9, rack 17, plate 11, arm 13 and to t e window. The movement of the arm will not only be apivotal' one on the pin 15 asa pivot but will be a sliding one on said pin as well, as is obvious because of the meshing of the pinion 9 with the rack 17 and because of the configuration of said rack. This arrangement permits the arm 13 to always exert 1t-s effort against the window centrally thereof whereby an easy and smooth operation of the window is obtained.

What we claim as our invention is 1. In a window regulator, a ivoted arm engaging the window and provided with a curved slot therein, a crank for swinging said arm on its pivot to raise or lower the window and means connecting said arm and cfank and extending through said curved s ot. a

2. In a window .regulator, an arm provided with a slot therein and capable of a pivotal movement and a movement longitudinally of its axis, a crank for actuating said arm to raise and lower the window and means connecting said arm and crank and extending through said slot.

3. In a window regulator, a support, a plate having a curved slot therein and mounted on said support, a shaft extending through said slot, a pinion on said shaft, a rack carried by said plate and meshing with said pinion, an operating arm engaging the window and movable with said plate and means for rotating said shaft.

4. In a window regulator, a plate, an elliptically-shaped rack carried by said plate, ashaft, a pinion thereon meshing with said rack, an arm secured to said plate and'engaging the window and means for rotating said shaft. I

5. In a window regulator, a plate, an elliptically-shaped rack secured to said plate, a pinion meshing with said rack, means for rotating said pinion and an arm pivoted to said plate'and toithe window.

6. In a windowregulator, aplatc, a curved rack secured to s aid plate, a pinion meshing with said rack, means for rotating said pinion, a slotted arm pivoted to the window and a pin extending {through the slot in said arm,

said arm being capable ofa slidable and pivotal movement ion said pin.

7. In a window regulator, a'support, an arm pivotally secured to said support and to the window, a plate provided with a curved slot therein and fastened to said arm, a shaft mounted ongsaid support and extending through said slot, a pinion carried by said shaft, a rack secured to said plate adjacent said slot andmeshing with said pinion and a crank for rotating said shaft.

8. In a window regulator, a support, a slotted arm pivotedto the window centrally thereof, a headed pin extending through the slot in said arm and carried by said support, a plate having acurved slot therein, said plate being secured to said arm, a rack fastened to said plate adjacent said curved slot, a shaft mounted in said support, a pinion carried by said shaft and meshing with said rack and a crank on said shaft for rotating the same.

9. In, a window regulator, a movable device having a curved slot therein, a rack, a pinion meshing with said rack, operating means, means connecting said operating and said pinion and extending through said slot and an operating arm engaging the window and movable with said device.

'10. ln'a window regulator, a movable e1- liptically-shapedrack, a toot-lied member meshing with said rack, a pivoted arm engaging the window and connected to said rack and means for ro'tatingsaid toothed member to raise or lower the window.

11. In a window regulator, a pivoted arm engaging the window, an elliptically-sha )ed rack associated with said arm, a toothed member meshing with said rack and means for actuating said toothed member to raise or lower the window.
